DSD 5.7 |Machine learning to find SARA prevalence in your herd

Subacute Ruminal acidosis, commonly referred to as SARA, could be robbing your herd of production. When pH dips too low for too long the biology of the rumen shifts, butterfat slides and overall health of the herd is negatively impacted. But how can you tell if your herd has SARA? This month we invite Dr. Eric Paquet and Felix Huot, from Université Laval in Quebec Canada to explain the method of using DHI milk samples to map the prevalence of SARA in the dairy herd of Quebec.
